Startswith()

Syntax: str.startswith(search_string, start, end)

Returns :

The return value is boolean. The functions returns

True

False

Use :

startswith() function is used to check whether a given Sentence starts with some particular string.
Start and end parameter are optional.
We may use them when we want only some particular substring of the original string to be considered for searching.

Endswith()

Syntax : str.endswith( search_string, start, end)

search_string : The string to be searched.

start : Start index of the str from where the search_string is to be searched.

end : End index of the str, which is to be considered for searching.

endswith() function is used to check whether a given Sentence ends with some particular string.

# Python code to implement startswith()
# and endswith() function.
 
str = "Lazyroar"
 
# startswith()
print(str.startswith("Geeks"))
print(str.startswith("Geeks", 4, 10))
print(str.startswith("Geeks", 8, 14))
 
print("\n")
 
# endswith
print(str.endswith("Geeks"))
print(str.endswith("Geeks", 2, 8))
print(str.endswith("for", 5, 8))
